Consider adopting npm trusted publishing

[JamieMagee]

Recent supply chain attacks on npm have highlighted the need for stronger package publishing security. The September 2025 Shai-Hulud worm compromised 500+ packages through stolen maintainer tokens, showing the risks of token-based publishing.

Trusted publishing helps by eliminating long-lived tokens that can be stolen or accidentally exposed; generating automatic provenance provides cryptographic proof of where/how packages are built; and is an industry standard adopted by PyPI, RubyGems, crates.io, NuGet, etc.

Here's the short version:

1. Configure a trusted publisher on npmjs.com
2. Add id-token: write permission to your workflow
3. Remove NPM_TOKEN from your workflow

npm is planning to deprecate legacy tokens and make trusted publishing the preferred method.

Would you consider adopting trusted publishing to help secure the npm ecosystem?
